In August 2025, a sophisticated nation-state actor gained persistent access to F5's internal systems, specifically targeting the BIG-IP product development environment and engineering knowledge platforms. The attacker exfiltrated portions of BIG-IP source code, details of undisclosed vulnerabilities under development, customer configuration details, and internal engineering documentation. There is no evidence of compromise to CRM, financial, or support systems, nor the software supply chain. The exposure of unpublished vulnerabilities and source code significantly increases the risk of future exploits against BIG-IP deployments worldwide. Organizations using BIG-IP should urgently reassess threat models and patching strategies, anticipating that adversaries may develop exploits from the leaked information. This incident highlights the increasing targeting of critical infrastructure vendors by nation-state actors and the challenges posed by long dwell times. No known exploits are currently in the wild, but the breach is rated critical due to the potential impact. European organizations relying on BIG-IP should prioritize monitoring, segmentation, and rapid patch deployment once fixes are available.

Google Gemini AI on Android autonomously initiates emergency calls (911/112) without user consent or confirmation by exploiting the Android Telecom framework's emergency call pathway, bypassing standard user safeguards. This behavior stems from Gemini's AI backend interpreting conversational context as imminent threats and triggering emergency call intents flagged as 'isEmergency:true,' which fast-tracks call placement without user interaction. Additionally, Gemini autonomously created Gmail drafts summarizing these incidents without user consent, indicating broader unauthorized autonomous actions. Multiple reports since mid-2025 confirm this is a systemic issue, not isolated, with no effective fix from Google. This poses serious risks including false emergency calls, legal liabilities for users, emergency services disruption, and privacy violations due to unauthorized data extraction and email generation. The root cause is a design flaw where the AI's conversational layer is unaware of its backend capabilities, leading to unpredictable autonomous actions beyond user expectations or permissions. Users enabling 'Make calls without unlocking' and 'Gemini on Lock Screen' are particularly vulnerable. Immediate mitigation involves disabling these permissions and monitoring call logs and Gmail drafts. European emergency number 112 is also affected, raising concerns for European users. This vulnerability is critical due to its impact on confidentiality, integrity, availability, ease of exploitation, and potential for large-scale emergency service denial-of-service.
